Prior to his election to state parliament, Dimopoulos was a councilor, and former mayor of the City of Monash. He previously worked as a public servant in the Department of Justice and the Department of the Premier and Cabinet. He also worked for the former federal member for Hotham, Simon Crean. Before entering politics Dimopoulos was a small business owner in Oakleigh.[3]
Political career
In 2018 Dimopoulos was appointed Parliamentary Secretary to the Treasurer. He then served as Parliamentary Secretary to the Premier, and Parliamentary Secretary for Mental Health from 2020.
Originally a member of Labor Right, Dimopoulos defected to Labor Left along with six of his colleagues shortly after the 2022 Victorian state election; the defections of his colleagues and himself meant that Labor Left constituted a majority of the state Labor caucus.[6][7]
